Published Feb 7, 2023 · Updated Mar 25, 2025

Stored XSS in Zyxel NBG-418N v2 firmware before V1.00(AARP.13)C0 allows remote attackers to inject scripts into the GUI Logs page. The Logs page stores attacker-supplied content without neutralizing script markup and executes it in an authenticated user's browser when opened. No authentication is required to plant the payload, but execution requires an authenticated user to visit the Logs page.
